The invention relates to a roof structure which is used in particular in tent construction.

It is already known to roof circular or oval surfaces or structures in such a way that that on solid supports, z. B. an external pull ring, sagging downwards Carrying ropes are anchored by running across them, preferably at right angles to them arranged tension ropes are intercepted so that

ίο in this way a fluttering of the roof covering, which occurs, for example, with suction forces, is largely prevented. These known so-called Suspended roofs have the disadvantage that the individual ropes or wires are of different lengths and require a comparatively high number of anchoring points; through the unequal The length of the ropes is also conditional on each traction rope having its respective length and load appropriate tensile force must be initiated. Also the roofing of elongated buildings where the suspension cables run from the ridge to the eaves and the tension cables from gable wall to gable wall, is not possible with this known method; rather, one was forced to do such to subdivide elongated buildings into truss fields.

These disadvantages are avoided in the roof structure designed according to the invention in such a way that that the tension ropes, which have a curvature opposite to the suspension ropes, in the

St 7798 V / 37 a are guided in the same direction as the carrying ropes and are in a force-locking connection with the carrying ropes via cross ropes, cross wires or the roof skin. This enables the roofing to be largely broken down and divided up. For example, the tensioning cables can be more or less arched, while the distance between the tensioning cables and the supporting cables and the mutual distance between the transverse cables of the respective roof cladding connecting the supporting cables and tensioning cables are adapted. The roof skin itself can be made of canvas or other webs of fabric, e.g. B. plastic sheets, or metal foils, translucent material, e.g. glass, or concrete. If only a single suspension cable and a single tension cable are alternately arranged, the result is a sawtooth-like roof covering in the longitudinal direction of the structure, while an undulating roof covering is achieved by arranging several suspension cables or tensioning cables next to one another. In the construction according to the invention, the covering of circular, circular or circular ring segment-shaped base surfaces takes place in such a way that the support cables and tension cables are anchored on the inside of the roof structure on a pull ring or partial pull ring. In the drawing, exemplary embodiments of the roof structure designed according to the invention are shown. Fig. 1 shows a roof construction with a sawtooth-like roof covering, Fig. 2 also a roof construction with a sawtooth-like roof covering with a different design of the supports, Fig. 3 a roof construction with a wave-shaped roof covering, Fig. 4 a roof construction with a circular segment-shaped plan. As Fig. 1 shows, the downwardly sagging supporting cables 1 and the upwardly curved tensioning cables 2 run in the same direction and are connected to one another by the roof skin 3, as shown in Fig. 2, or by cross cables 4 or cross wires. The cables 2 are tensioned by turnbuckles or other generally known devices that are not shown in the drawing. In the wave-shaped roof construction according to Fig. 3, two supporting cables 1 and two tensioning cables 2 are arranged in the wave crests and in the wave troughs, which are in a force-locking connection via transverse cables 4. In the case of the roof construction in the shape of a segment of a circle according to Fig. 4, the supporting cables 1 and the tensioning cables 2 are anchored to an inner partial ring. In the exemplary embodiment shown, this partial ring consists of a spatial tension member which consists of the main safety rope 5, further safety ropes 6, 7 and transverse ropes 8 connecting the safety ropes. The free edges of the membrane-like tensioned roof skin 3 can, as FIG. 2 shows, be secured by reinforcing cables 9. Paten ta ν s PR O c η E: 1.
